CLEVELAND — Detroit Lions all-pro receiver Calvin Johnson is active and will start Sunday's game against the Cleveland Browns. The man known as Megatron missed Week 5's loss to the Green Bay Packers with a sprained right knee.

Johnson took the field 2½ hours before kickoff to test the knee. He looked smooth running in and out of his breaks without a visible hitch in his stride while catching passes from quarterback Matthew Stafford.

Browns owner Jimmy Haslam stood on the field watching Johnson go through the route tree.

The 6-5, 236-pound wideout ranks second on the Lions with 21 receptions for 312 yards.

He has been extremely durable, missing just five games since the Lions chose the former Georgia Tech receiver second overall in the 2007 draft.

Browns cornerback Joe Haden expected Johnson to play and looked forward to testing himself against the game's best receiver. Haden has yet to allow a touchdown this season despite facing the likes of Miami Dolphins speed receiver Mike Wallace, Baltimore's Torrey Smith, Minnesota's Greg Jennings, Cincinnati's A.J. Green and Buffalo's Stevie Johnson.

Since the beginning of the 2011 season, Johnson has tallied 3,957 receiving yards, the most in the league during that span.

"Covered or not covered, the ball is still going to come his way," Haden says. "You just have to play tight coverage and keep your focus every play against him."
